World's Healthiest Herbs

Rosemary

Pairs well with: Potatoes; citrus; honey; garlic; onions; chile peppers
May help: Enhance mental focus, fight foodborne bacteria.

In ancient Greece, scholars wore rosemary garlands to help them study—and one recent study found that people performed better on memory and alertness tests when mists of aromatic rosemary oil were piped into their study cubicles. Rosemary is often used in marinades for meats and poultry, and there’s scientific wisdom behind that tradition: rosmarinic acid and other antioxidant compounds in the herb fight bacteria and prevent meat from spoiling, and may even make cooked meats healthier. In March, Kansas State University researchers reported that adding rosemary extracts to ground beef helped prevent the formation of heterocyclic amines (HCAs)—cancer-causing compounds produced when meats are grilled, broiled or fried.

Turmeric

Pairs well with: Garlic; citrus; ingredients in curry powder, such as coriander & cumin
May help: Quell inflammation, inhibit tumors.

In India, turmeric paste is applied to wounds to speed healing; people sip turmeric tea to relieve colds and respiratory problems. Modern medicine confirms some solid-gold health benefits as well; most are associated with curcumin, a compound in turmeric that has potent antioxidant and anti-inflammatory properties. Curcumin has been shown to help relieve pain of arthritis, injuries and dental procedures; it’s also being studied for its potential in managing heart disease, diabetes and Alzheimer’s disease.
Researcher Bharat Aggarwal is bullish on curcumin’s potential as a cancer treatment, particularly in colon, prostate and breast cancers; preliminary studies have found that curcumin can inhibit tumor cell growth and suppress enzymes that activate carcinogens.

Chile Pepper

Pairs well with: Ginger; chocolate; beans; beef
May help: Boost metabolism.

Chiles, which create sensations of heat, from mild to fiery, are especially prized in hot climates since, ironically, the spice helps trigger the body’s natural cooling systems. Studies show that capsaicin—a pungent compound in hot chiles—revs up the body’s metabolism and may boost fat burning, but the jury is still out on whether that translates to long-term weight loss. Recent research found that capsinoids, similar but gentler chemicals found in milder chile hybrids, have the same effects—so even tamer sweet paprika packs a healthy punch. Capsaicin may also lower risk of ulcers by boosting the ability of stomach cells to resist infection by ulcer-causing bacteria and help the heart by keeping “bad” LDL cholesterol from turning into a more lethal, artery-clogging form.

Ginger

Pairs well with: Soy sauce; citrus; chile peppers; garlic
May help: Soothe an upset stomach, fight arthritis pain.

Traditionally used to relieve colds and stomach troubles, ginger is rich in inflammation-fighting compounds, such as gingerols, which some experts believe may hold promise in fighting some cancers and reducing arthritis pain. In a recent study, people who took ginger capsules daily for 11 days reported 25 percent less muscle pain when they performed exercises designed to strain their muscles (compared with a similar group taking placebo capsules). Another study found that ginger extract injections helped relieve osteoarthritis pain of the knee. And ginger’s reputation as a stomach soother seems deserved: studies show ginger extracts can help reduce nausea caused by morning sickness or following surgery or chemotherapy, though it’s less effective for motion sickness.

Cinnamon

Pairs well with: Cloves; nutmeg; allspice; chocolate; fruit; nuts
May help: Stabilize blood sugar.


Cinnamon was prized by King Solomon and used by the ancient Greeks and Romans to boost appetite and relieve indigestion. A few studies suggest that adding cinnamon to food—up to a teaspoon a day, usually given in capsule form—might help people with type 2 diabetes better control their blood sugar, by lowering post-meal blood-sugar spikes. Other studies suggest the effects are limited at best.
